Here I have found what is on the record … a remastered sound.
https://www.youtube.com/watch?v=h3WJiqc_bEsHere I have found a live performance of his guitar.
https://www.youtube.com/watch?v=srwxJUXPHvEAs I listen to the two different videos, it sure would appear that in the studio, a lot of tweaking went on with the Harrison guitar track. Also in the live video that guitar sounds a bit out of tune to me but it is different than the first, which suggests to me, Harrison could not recreate that studio sound live either.
Just find something close and be happy
You can go online and check out Wiki (and other sites) for information about how the song was recorded. This might give you tips as what to look for in the way of a guitar voice to use.
As an example:
I have created only one Beatles style and that was for the song "And I Love Her". When recording the song I wanted to know who all was doing the backup vocals. As it turned out it was nobody, the Studio just doubled tracked the one vocal track. When I did my recording and when doing the song live, I use the Standard Duo set up with 14% reverb on the setting. What did the Beatles do when they performed the song live? I have no idea.
